Title: Centrifugal force steel pipe concrete column and manufacture thereof
Inventor: OKAMOTO TATSUO
IPC: E04B1/94
Filed: 1993-11-15
Abstract: PURPOSE:To obtain a centrifugal force steel pipe excellent in fireproof performance regardless of small sectional area at a low cost by constructing a concrete molded body in a centrifugal force steel pipe by plural layers (a layer where a reinforcing material is mixed and a layer without a reinforcing material). CONSTITUTION:A steel pipe 1 having a designated length is rotated on the shaft center X. Concrete where a reinforcing material is mixed is supplied into the steel pipe 1. By the centrifugal force with the rotation, the concrete is compacted to form a reinforced concrete layer 2A. Subsequently, concrete to which a reinforcing material is not mixed is supplied into the steel pipe 1, and similarly the concrete is compacted by the centrifugal force to form a non-reinforced concrete layer 2B. Mortar M is filled in the cylindrical concrete. Thus, even if it has a sectional area smaller than that of the steel pipe concrete column formed by simply pouring concrete in the steel pipe, it is possible to obtain more excellent fire-proof performance.

Abstract: PROBLEM TO BE SOLVED: To facilitate any adjusting operation on the mounting position of an eaves gutter by screwing each of two butterfly nuts in the top and bottom of a bolt unrotatively inserted into a square hole, and pinchingly clamping an eaves lifting sling engaged with this eaves gutter via a long hole, in this eaves gutter supporter. SOLUTION: An attached part 20a of a stopper 20 is clamped tight to a fascial board at the edge of the eaves, while a lifting fitting 30 is fitted in a sectional U-shaped holding part 20c at a tip part, and a square pole-form body part 40a of a bolt 40 is inserted into two quadrangular bolt insertional holes 20g and 20g in stalled in this holding part 20c and a long hole 30d of the lifting fitting 30, making this bolt 40 unrotatively engage with it, and further two butterfly nuts 50 and 50 are screwed in two thread parts 40b and 40b at the top and bottom of the bolt 40, and thus this lifting fitting 30 is pinched and clamped tight. Therefore, after a sectional U-shaped eaves gutter is engaged with two engaged parts 30a and 30b of the lifting fitting 30, only the butterfly nut at the upper side is operated and thereby a position to the edge of the eaves gutter is adjustable.  In addition, the butterfly nut 50 at the lower side is merely operated and, after a position of the lifting fitting 30 is adjusted, the eaves gutter can be engaged with this lifting fitting 30 as well.

Inventor: KIKUTA SAKAE
IPC: F02D41/08
Filed: 1994-11-18
Abstract: PURPOSE: To prevent an air flow sensor from making too large or small measurement and reduce a harmful discharged gas component by restricting either of intake amount information or fuel supply amount to a prescribed restricting range if an internal combustion engine is in a lower load operating condition than a decelerating operating condition or a prescribed load. CONSTITUTION: ECU 50, when a throttle valve 9 is fully opened and such decelerating operation as a bypass valve 42 is opened starts, computes the first clip value from theoretical frequency which is computed from the opening of an ISC11, and then the second clip value by giving tailing to an intake amount at the starting time of decelerating operation. A larger one of both the clip values is taken as an upper limit clip value, and when intake amount information obtained from the outputs of an air flow sensor 6 and a crank angular sensor 23 exceeds the upper limit clip value, a fuel injection amount is determined based on the upper limit clip value to control a fuel injection valve 3. A lower limit clip value is computed in the same way to add some restriction to the fuel injection amount.
